This model is discontinued
AirTAC has phased out the ACP series. You can still order this code here: we ship the current replacement ACEJ20X160-50, the same code under the new prefix. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50
The AirTAC ACPJ Adjustable Compact Cylinder ACPJ20X160-50 is a double acting, double rod, adjustable stroke DIN-standard tight/compact air cylinder with a Ø20mm bore and 160mm stroke, M5×0.8 air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACEJ20X160-50 (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50
This AirTAC ACPJ20X160-50 is a double acting compact cylinder with an adjustable extend stroke: a stop screw trims the 160 mm stroke anywhere within a 50 mm window, giving a usable range of 110-160 mm on site.
The 160 mm stroke exceeds the 100 mm standard maximum for bore 20, so this unit is made to order. Note the adjuster is a mechanical end stop only: on air loss the piston still drifts, so it never holds a load. This model is discontinued; the current-production direct is the ACEJ20X160 (swap the P for an E), and buyers should confirm ISO 21287 mounting dimensions before swapping since the ACP is DIN-standard.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACEJ20X160-50 (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø20mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 118 N |
| 0.7 MPa | 165 N |
| Max (@1.0 MPa) | 24 kgf |
ACPJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Replacement mapping (swap P for E): ACP→ACE, ASP→ASE, ATP→ATE, ACPD→ACED, ACPJ→ACEJ. ACP-family: ACP (double acting), ASP / ATP (single acting push / pull), ACPD (double rod), ACPJ (double rod, adjustable stroke).
Where the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50 Is Used
Fixture clamping on a compact machining jig
The 50 mm adjustment window lets one cylinder serve several part heights on a milling fixture, trimming the extend stroke between 110 and 160 mm without changing hardware.
Height-setting stop on an assembly gantry
The stop screw acts as a repeatable mechanical end stop for the extend stroke, ideal for setting a fixed stop height on a shallow overhead gantry where a full-length profile cylinder will not fit.
Replacing the Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50 with the ACEJ20X160-50
If you need the rod held under load at mid-stroke, remember the stop screw only trims the extend stroke and cannot lock it. Mounting is FA/FB flange or LB foot on the standard face, and the optional -S magnet enables CMSE / DMSE switches - without the -S code there is no magnet. This model is discontinued; order the ACEJ20X160 as the current replacement and confirm ISO 21287 mounting dimensions.
Replacement checklist
- ✓ Current-production ACE → ACEJ20X160-50
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPJ Adjustable Compact Cylinder ACPJ20X160-50 FAQ
At 0.5 MPa it pushes 157.1 N and pulls 117.8 N; at 0.7 MPa push rises to 219.9 N and pull to 164.9 N. The theoretical maximum at 1.0 MPa is 32 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with proof pressure of 1.5 MPa (215 psi), speed 30-500 mm/s, and the port is M5x0.8 because port size depends only on the 20 mm bore.
The -50 code is a 50 mm window: an external stop screw shortens the 160 mm extend stroke on site to any length from 110 to 160 mm, with fixed TPU bumpers at both ends. It is a mechanical stop, not a mid-stroke lock. The ACPJ family is discontinued; the ACEJ20X160 is the current ISO 21287 direct with the same bore, stroke and force class - confirm the ISO 21287 mounting dimensions before swapping.
